Exhaust gas comes out of the engine into the first turbo and through an external gate if there is too much for the first turbo to use.

Then it goes onto the second turbo.

Once on boost the first turbo should offer very minimal restriction to the exhaust gas flow to the second one as it will be bypassed by most of the gasses.

The two compressor outlets are then Y pieced together before the plenum, so if either of them makes any boost then the engine gets it.



What is the reason we arent all doing that?


Seems like a very good idea to me TBH, but i know very little about compounding charging other than its not common, so from that i would assume there is a reason not to do it?
